Titration between phosphoric acid and NaOH. For Ka1, calculate: 1/2 equivalence point, equivalence point, and after 7.5 mL added. For Ka2, calculate: 1/2 equivalence point, equivalence point, and after 17.5 mL added. Please show step by step, thank you! 1 pH mL NaOH Phosphoric A...
Prove both sides of theorem 2.1.1 #1010) absorption law: and
a certain center uses both form and form b if form a is used 4 times more than form b and in the course of one day they use form a and b 750 times how many times was form a used
The statement "form follows function" means function over form, form over function, form and function together, or function under form. I think it is form over function.
o Why don't knots form a group? o Why do braids form a group? (What in knot theory does form groups) o Why don't knots form a group? o Why do braids form a group? (What in knot theory does form groups)
Define a relation R on Z as xRy if and only if x2+y2 is even.Prove R is an equivalence relation.Describe its equivalenceclasses.
Assuming that Ka is 1.85 *10-5 for acetic acid, calculate the pH at one-half the equivalence point and at the equivalence point for titration of 50mL of 0.100M acetic acid with 0.100M NaOH.
A 25.0 mL sample of a solution of the weak base aniline, C6H5NH2, requires 25.67 mL of 0.175 M HCl to reach the equivalence point. (Kb for aniline = 4.0 x 10–10)C6H5NH2(aq) + H3O+(aq) ? C6H5NH3+(aq) + H2O(l)What is the pH at the equivalence point of the titration and at the half...
